One hundred twenty households were selected, 60 from Abol and 60 from Godere weredas.

Formal and informal survey methods were used to collect information of secondary data and response on structured questionnaires from May 2014 to July 2014. The study was aimed at identifying opportunities and constraints of beekeeping in Gambella zuria (Abol) and Godere weredas, South West Ethiopia. Significant disease reduction over control was also observed in all the treatments, but propolis (45.65%) and turmeric powder (43.48%) showed the best results in wilt disease reduction.

solanacearum, turmeric powder (1.8 X 109) showed the highest count compared to other amended soil. However, in increasing the avirulent count of R. solanacearum occurred in all the treated soil, but propolis (8.2 X 107) and cow dung (1.1 X 108) showed the lowest count. Significant difference in soil pH and per cent organic matter (OM) occurred in all the amended soil as compared to control. Data on pH, organic matter, total cfu/ml and avirulent cfu/ml of the treatment applied soil and per cent disease index (PDI) of bacterial wilt of potato were recorded.

Sun dried cow dung 30 t/ha, aqueous extraction of turmeric powder 30 kg/ha and propolis 5 lit/ha were applied to the inoculated soil by mixing with field soil in SAU (Dhaka) and BARI (Gazipur). cow dung, bee propolis and turmeric powder were applied to amend the Ralstonia solanacearum infested soil of potato.
